   Areas affected...portions of eastern OH into western WV and western
   PA

   Concerning...Severe potential...Severe Thunderstorm Watch likely 

   Valid 182348Z - 190045Z

   Probability of Watch Issuance...80 percent

   SUMMARY...A mature squall line continues to advance eastward with
   severe gust potential. This line is expected to advance east of
   ongoing Severe Thunderstorm Watches 436-437, necessitating a
   downstream Severe Thunderstorm Watch issuance.

   DISCUSSION...A mature QLCS continues to propagate eastward, with
   recent reports of measured gusts in the 50-68 mph range in the past
   hour or so. This line will continue advancing eastward into a
   moderately unstable airmass, which will support additional strong to
   potentially severe gusts. As such, a downstream Severe Thunderstorm
   Watch will be needed soon.
